Airflow 1.9 - SSHOperator 似乎不起作用？

Question

已升级到 v1.9，我很难让 SSHOperator 正常工作。它正在使用 v1.8.2。

代码

dag = DAG('transfer_ftp_s3', default_args=default_args,schedule_interval=None)

task = SSHOperator(
       ssh_conn_id='ssh_node',
       task_id="check_ftp_for_new_files",
       command="echo 'hello world'",
       do_xcom_push=True,
       dag=dag,)

错误
